IMPROVEMENT IN D'AMP ERS FOR FIRE-PLACES.

Specification forming part of Letters Patent No. 126,927, dated May 21,1872.

Specification describing a new and Improved Damper for-Fire-Places,invented by JOSEPH BRIDGHAM, of the city, county, and State. of NewYork.

Figure 1 represents a perspective view of a grate, showing the supportsfor my improved damper for fire-places. Figs. 2 and 3 are perspectiveviews of the device, showing it entirely of metal or of stone, withmetal ends, respectively. L

Similar letters of reference indicate corresponding parts.

This invention relates to a new damper for fireplaces, to beused inchimneys above grates for regulating the draught. The invention consistsin providing the damper with projecting pivot-pins and stops at the endsand in the use of metallic sockets for its support built into the wall.

The advantages of this, arrangement are, first, that the damper can beswung open or closed with greater ease than heretofore, as it isproperly pivoted in reliable supports; second, that the cheeks and thelire-back are not wornby the motion of the damper; and third,

that the latter cannot fall out of its own accord, though it can beremoved when desired.

A in the drawing represents the damper. When made of metal, as in Fig.2, it is provided with projecting pivot-pinsaa at the ends .nearthelower edge, as shown, and also with a backwardly-projecting pin, c,at or near the middle. The pins a are, when the damper is in position,fitted into sockets B, which are built into the ends of the fire-placeback of the cheeks d of the same, as indicated in Fig. 1. Every socket Bhas a downwardly-projecting lip, 0, whereby its firm hold in thefire-place is insured. The damperAis, after the sockets have been builtinto the wall, so applied thereto, that the pins a rest in the sockets,and constitute the pivots of the damper. The ears I) rest against thecheeks d when the damper is closed, and prevent the same from fallingforward. The projection c, at the back of the dam per preven ts it fromfallin g flat when swun g back, and facilitates the application ofdevices for swinging it forward again.

When the damper is made of stone it is provided with metal caps 0 O atthe ends, which have the projecting-pinsaand ears b,the same as themetallic damper for the same purpose, and as shown in Fig. 3. l

Having thus described my invention, I claim as new and desire to secureby, Letters Patent- 1. As a new article of manufacture, the damper A,provided with side-pins a a, rear pin 0, and lugs b b, to adapt it touse in the manner set forth.

2. As an article of manufacture, the socket B, having the lip e adaptedto be used in the manner and for the purpose described.
